CABLE-'THIMBLE.

Specification of Letters Patent.

Patented July 29, 1919.

To all whom it may concern Be it known that we, MAX M. GOLDMAN, a citizen of the United States, residing at Somerville, county of Middlesex, and State of Massachusetts, and MICHAEL J CONNELLY, a citizen of the United States, residing at Boston, county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Cable- Thimbles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to thimbles for use with cables, ropes, etc., in general rigging work. In prior cable thimbles, as far as we are aware, the metal has been of uniform thickness throughout, and this thickness has not been sufficient to stand up under severe strains. Consequently, the thimble frequently bends and slides one point or end past the other, which weakens the thimble, renders it more or less unsightly and tends to cut or chafe the strands of the rope or cable. The prior thimbles also have frequently collapsed from the strains of the cables, bending in the portion of the loop opposite the free ends. It is the object of this invention to overcome these defects, and the manner in which it is accomplished will be described in the following specification, with reference to the drawings, in which Figure 1 is an elevation of a cable thimble with the cable spliced in position.

Fi 2 is an end view of the thimble shown in Fig. 1, but with the cable removed.

Fig. 3 is a section on either of the lines 13-13 or A-A of Fig. 1.

Fig. 4 is a section taken on the line CC of Fig. 1.

Referring to the drawings, the thimble 1 is stamped, drawn, cast or otherwise formed from suitable metal, such as iron or steel, and is preferably made in the general form of an oval, as shown, with the exception that one end is more or less pointed instead of being rounded, as is generally the case with true ovals. The shell of the thimble has a groove 2 formed entirely around the outside, which is adapted to receive the cable 3, as

copies of this patent may be obtained for five cents each, by addressing the shown, particularly in Fig. 1. The shell 1 has a reinforcing member 4 on the inside, preferably made integral with it. This reinforcing member extends around the bent portion of the loop or oval and terminates short of the free ends of the shell. The ends of the reinforcing member also are preferably chamfered off, as shown at 5.

It is not necessary as far as strength is concerned, to have the reinforcing member extend clear around the entire portion of the shell, as the maximum strength will be obtained by having it extended substantially over the majorportion only, though this may be varied in extent. This not only saves in the amount of metal necessary for producing a heavy thimble to stand the strain, but it also has the useful purpose of leaving open spaces, such as 6 and 7 to permit the application of seizing or marline strands 8 and 9 to hold the cable 3 securely in place around the thimble shell.

After the cable is passed around the thimble, it may be spliced in the usual way, as shown at 10. When a thimble is made in accordance with our invention, it will be found to be very much stronger than prior types of thimbles, but with minimum weight of metal therein. It will also be found that the seizing strands can be placed around the cable and shell, just as easily as in the nonreinforced types of thimbles now found on the market, as there is ample space for performing such operation.

Having described our invention, what we now claim is:

A cable thimble consisting of a grooved shell portion bent into substantially oval shape with the free ends adjacent each other and a reinforcing member extending along the bent portion of the inside of said shell, said thimble having an open space between the ends of the reinforcing member and the said free ends of the shell for the reception of marline strands.

In witness whereof, we have signed our names this 27th day 1919.

hereunto of March,

MAX M. GODDMAN. MICHAEL J CONNELLY.
